In house AM Radio Interference during the day that disappears at night?

Do you have an electric water heater, or gas?
If electric, is the power on a special circuit that controls usage by time of day?
Does the interference disappear all night or come back in the early hours?

i have a gas water heater, and as far as I know it has its own breaker, but its alway on (no timer or time control.)

I do have a smart meter for my water, but it doesn't emit any noise because I thought of that myself and when I put my radio upto it it didn't do anything, as for my gas meter, it too is a smart meter, but it doesn't do anything either when I hold the radio up to it, the only things around the house that makes any major noise is my refrigerator and stove, but you have to be right ontop of them with the radio to hear anything, but I wouldn't think that the stove and refrigerator would make any difference between night and day as far as what kind of RFI/EMI noise it puts out, unless the refrigerator and stove is backfeeding the noise through the house's wiring?

The refrigerator is actually the only appliance in my house that I have found that comes closest to producing the same RFI/EMI interference that my radio is picking up, but I didn't realize refrigerators were capable of putting out RFI and EMI noise, because I wouldn't of thought of a refrigerator as having a SMPS in it, but that doesn't explain why I am hearing the noise strongly in the basement in just one spot, and why the noise goes away at night.
